I think the problem here is that it adds complexity, cost, may impact support thus contracts and it's not clear if it has saved you any outage. It becomes belief engineering. I think more useful would have been to figure out how you can replace that device with data in the shortest possible window, to cover every unexpected failure mode with smallest possible outage. -- ++ytti
